Cutting apparatus

ABSTRACT

An apparatus for cutting and dispensing sheet material from a roll of material comprising rack means carried by a pair of standards for supporting an elongated roll of sheet material. The sheet material is fed over a cutting surface under a pressure bar which holds an end of the sheet material on the cutting surface after a cutting blade severs the sheet material. An arm extends outwardly from adjacent the middle of the cutting surface for measuring the length of the material to be cut. The arm also provides means over which the material can be automatically folded upon cutting.

1 CUTTING APPARATUS This invention relates to a dispenser for sheet material and-more particularly to adispenser which is provided with means for measuring the material being cut, as well as folding the-material after such has been cut.

particularlyin hospitals and motels.

One of the problems provided with dispensers'heretofore developed is that there is no readily available means of measuring the length of the material and they require expensive heavy duty cutter bars.

Accordingly, it is an important object of the present invention toprovide a dispenser o'fdisposable material which can be readily transported and the material can be cut and folded in'predetermined measured lengths.

Another important object of the present invention is to provide a simple dispenserof disposable material which utilizes a pressure rollerfor holding the material while a cutter is moved laterally acrossthe material.

Another important object of'the present invention is to provide a dispenser, of disposable material which utilizes a protective bar for the cutting assembly, as well as provides a meansfor lifting the dispenser.

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification, and by reference to the accompanying drawings forming a part thereof, wherein an example of the invention is shown and wherein:

FIG. lis a perspective view of a cutter assembly constructed in accordance with the present invention.

FIG. 2 is a transverse sectional view taken along the lines 2-2 of FIG. 1,

FIG. 3 is a perspective view illstrating a modified form of the invention,

FIG. 4 is a transverse sectional view taken along the lines 44 of FIG. 3 illustrating the cutter assembly, as well as the means for folding and measuring the material being cut, and

FIG. 5 is en enlarged front elevational view, with parts broken away, illustrating a cutter utilized in the dispenser.

Referring in more particular-to the drawings, there is illustrated an apparatus for cutting and dispensing sheet material from a roll of sheet material comprising a pair of spaced standards A with rack means carried by standards A for supporting an elongated roll of sheet material '3. A cutting surface is carried between the spaced standards. A horizontally disposed elongated bar is carried between the standards above the cutting surface with a cutting blade C mounted thereon for reciprocal sliding movement. Apressure bar is carried on the cutting surface adjacent the cutting blade. The sheet material extends from the roll B between the pressure bar D and the cutting surface so that the pressure bar holds an end of the sheet material on the cutting surface after the cutting blade severs the sheet material. An arm E extends outwardly from the cutting surface for indicating the length of the material cut.

Referring to FIG. 1, there is illustrated a heavy duty dispenser which can be located in a storage room or the like, ofa motel or if desired, rolled to a dining room so that individual sheets can be cut adjacent the tables. The A-shaped standards A may be constructed of any suitable material, such as channel members, and supported on casters 10. The standards A are joined by lower cross bars 12 and 13, respectively. A rack constructed of angle-iron 14 is carried by each of the A- shaped standards for supporting :the ends of apipe '15 upon which the rolls of disposable material B is carried. Positioned adjacent'the upper-portion of the standards A is a relatively flat cutting surface '16 which has an elongated groove '18 disposed therein. The cutting surface 16 may be constructed of a channel member which is split to define the groove 18. Positioned directly below the groove '18 is an inverted channel member 20a upon which the outwardly extending arm E is supported.

An elongated bar' 20 is carried between the standards A adjacent the upper foremost corners, Positioned on the bar 20 is the cutter, which includes a square metallic block 24, which has a hole extending therethrough, through which the bar 20 passes. The block'has threespaced pins 26 extending forwardly-therefrom for receiving a steel blade 28. The blade has a sharpened forward and trailing edge 30 and 32, respectively. An outer plate 34 is secured over the blade by a screw 36 for locking the blade to the block 24. The lower edge of the blade 28 extends within the groove 18 so that as such is pulled across the apparatus it se'vers the disposable material 36 extending from the roll of sheet material B. A pivotal pressure bar D isprovided for holding the end of'the sheet material 36 on the cutting surface 16 after the material has been severed. The pressure bar includes a pair of disposed arms 38 which arepivotally connected by their lower end to an upper portion 40 of the standards A. The free ends of the arms 38 have a roller 42 journalled therebetween. When the sheet material 36 is being threaded under the pressure roller it is raised to the position illustrated in FIG. 1. Once the material has been threaded over the cutting surface 16 the pressure bar'D is pivoted forward so that v the roller 42 will rest thereon. It is important that the material can be drawn freely under the roller 42 when such is in the lowered position so that the material can be readily taken off of the roll. However, it is equally important that the material can be rerolled on the roll B in instances where too muchof the material has been drawn thereoff. The pressure exerted by the pressure bar 42 aids in rewinding the material on the roll.

The arm E extends outwardly from the cutting surface 16 for indicating the length of the material to be cut. The arm E is constructed of a pair of tubular members 44 and 46 wherein the member 44 is allowed to telescope within the member 46. Calibrations in the form of marks 48 may be provided on the members 44 and 46 to indicate the distance from the groove 18. The inner end of the telescoping member E is journalled by means ofa bolt 50 and a nut 52 in the channel member 20 carried beneath the groove 18. This enables the member E to be folded under the cutting surface 16, such as illustrated in FIG. 1, when not in use. The arm E has a double purpose in that it indicates the length of material drawn off the roll B plus, it provides a means for automatically folding the material cut in half once severed. Such is very convenient when it is desired to cut a number of table cloths for relatively small square tables, such as is utilized in restaurants. The material is merely drawn off of the rolls and the cutter C is moved back and forth. The material automatically folds over the arm E when severed.

FIG. 3 illustrates a modified form of the invention wherein a lightweight stand is utilized and the standards A are constructed of relatively lightweight wrought iron. Like reference characters are utilized on the modified form of the invention for like and corresponding parts. One of the primary differences is the manner in which the pressure bar D is mounted, adjacent the pressure plate. Such includes a channel member 50a which is welded on the standards adjacent the cutting surface. The rod 42 fits within the opposed channels 50 and rests on top of the cutting surface 16 for holding the end of the material after such has been severed.

The roll of material B is supported between the cross braces 14 by U-shaped members 52 carried thereby. It is noted that the roll of material B is illustrated in FIG. 2 as being held in position on the angle member 14 by the spaced tabs 54.
